Specialized carbon crank on a standard BB?

I know that Overend used the Spesh carbon crank on his SS Rockhopper a few years back...and from what I read...the older cranks were able to use a Vumaquad bottom bracket to run the crank.

I just noticed Overend using a Specialized carbon crank on a 2014 Crave. The Crave uses a standard threaded bottom bracket. Anyone know how it could have been installed...or it it just a standard Lightning crank that was re-labeled?
